The 22 mb (13 MHz) region is a very interesting section of the HF spectrum,
and behaves both as a short-haul band for daytime propagation, and as a
long-haul band for night-time signals.
Here in Melbourne, the band is very active in our mid-afternoons, with
longpath (darkness) propagation from Europe, Africa and the Middle East, and
shortpath (daylight) from Asia.
This is how the band looked between 0500 and 0530 on Friday July 16 2010,
from one of my favourite field monitoring sites in the Warrandyte State
Park, 20 km east of Melbourne central - the exact location was on South
Hill, adjacent to the Fiddler Gully historical gold mining area. I used the
little Eton E5, with a 3 m antenna in a bush, near old mine shafts.
